The purpose of this text is to introduce the reader to the three fundamental liberal arts: grammar, logic, and rhetoric. These three disciplines, together called the Trivium, formed the foundation of the system of education that held sway in the West from ancient to modern times. Grammar is the art of combining the symbols that we call words into sentences. Logic is the art of reasoning to achieve knowledge of reality as it is. Rhetoric is the art of sharing ideas and of persuasion.
